Subject [jira] [Commented] (DERBY-5748) Native user authentication: SYSCS_UTIL.SYSCS_MODIFY_PASSWORD accepts old password
Date Mon, 07 May 2012 13:34:57 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5748?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13269605#comment-13269605
] 

Rick Hillegas commented on DERBY-5748:
--------------------------------------

Password vetters often prevent you from re-using any previous password, not just the current
one. This would involve maintaining an audit history. I agree that password strength checking
would be useful too. For the moment, applications will have to perform these services themselves.

> Modifying the password to the same as the old one will reset the timeout specified in
derby.authentication.native.passwordLifetimeMillis.
> This means that a lazy user can subvert the security policy embodied in the timeout.
It would be an improvement to require a different one.
> Of course, we don't currently have any password strength checking either, so it may not
be worth just implementing this change without making some configurable strength checking
also.
